The sustainable production of green hydrogen via water electrolysis necessitates cost-effective electrocatalysts. By following the circular economy principle, utilization waste-derived catalysts significantly promotes development energy. Currently, diverse have exhibited excellent catalytic performance toward evolution reaction (HER), oxygen (OER), and overall (OWE). Herein, we systematically examine recent achievements in electrocatalysts for electrolysis. general principles design efficient are discussed, followed by illustration current strategies transforming wastes into Then, applications (i.e., carbon-based catalysts, transitional metal-based heterostructure catalysts) HER, OER, OWE reviewed successively. An emphasis is put on correlating catalysts' structure-performance relationship. Also, challenges research directions this booming field finally highlighted. This review would provide useful insights design, synthesis, electrocatalysts, thus accelerate economy-driven energy scheme.

Abstract Directly seawater electrolysis would be a transformative technology for large‐scale carbon‐neutral hydrogenproduction without relying on pure water. However, current splitting is challenged by detrimental chlorine chemistry, the sluggish kinetics, and existence of impurities/precipitates, making it more difficult than water splitting. So far, tremendous efforts have been made to develop electrocatalysts boost electrocatalytic hydrogen evolution reaction (HER) oxygen (OER) activities seawater‐based electrolyzers. To get further insights into achievements future perspectives catalysts electrolysis, general principles are summarized comprehensive optimization, ranging from active sites, electrochemical interface, electron transfer path, fully improve performance electrolysis. Then, aiming at different challenges cathode anode unique strategies design effective cathodic anodic catalysts, such pH criterion, selective HER/OER, Cl − blocking layers, discussed, respectively. Also, several fields which worthy exploration as rational extensions developing toward practical applications put forward.

The development of efficient electrochemical seawater splitting catalysts for large-scale hydrogen production is great importance. In this work, we report an amorphous Co-Mo-B film on Ni foam (Co-Mo-B/NF) via a facile one-step electrodeposition process. Such Co-Mo-B/NF possesses superior activity with small overpotential 199 mV at 100 mA cm−2 evolution reaction in alkaline seawater. Notably, also maintains excellent stability least 24 h under electrolysis.

Green hydrogen production from renewably powered water electrolysis is considered as an ideal approach to decarbonizing the energy and industry sectors. Given high-cost supply of ultra-high-purity water, well mismatched distribution sources renewable energies, combining seawater with coastal solar/offshore wind power attracting increasing interest for large-scale green production. However, various impurities in lead corrosive toxic halides, hydroxide precipitation, physical blocking, which will significantly degrade catalysts, electrodes, membranes, thus shortening stable service life electrolyzers. To accelerate development electrolysis, it crucial widen working potential gap between oxygen evolution chlorine reactions develop flexible highly efficient purification technologies.
